description |
The debug tracepoint in Dnsmasq._output_hosts_file is extraneous and causes unnecessary performance overhead due to string formating when creating lots (> 1000) ports at one time.
The trace point is unnecessary since the data is being written to disk and the file can be examined in a worst case scenario. The added performance overhead is an order of magnitude in difference (~.5 seconds versus ~.05 seconds at 1500 ports). |
[Impact]
The debug tracepoint in Dnsmasq._output_hosts_file is extraneous and causes unnecessary performance overhead when creating lots (> 1000) ports at one time.
The trace point is unnecessary since the data is being written to disk and the file can be examined in a worst case scenario. The added performance overhead is an order of magnitude in difference (~.5 seconds versus ~.05 seconds at 1500 ports).
[Test Case]
1. Deploy OpenStack using neutron for networking
2. Create 1500 ports
3. Observe the performance degradation for each port creation.
[Regression Potential]
Minimal. This code has been running in stable/juno, stable/kilo, and above for awhile.
[Other Questions]
This is likely to occur in OpenStack deployments which have large networks deployed. The degradation is gradual, but the performance becomes unacceptable with large enough networks. |
